ASTM/AISI Standard Alloy Round Bar AISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint.

AISI 4130 steel is a low alloy steel that is used in structural designs that may be found in applications such as aircraft engine mounts or welded tubing. It is well known for its ease of welding and ability to harden in commercial applications. It is commonly referred to as chromium-molybdenum steel.

Cold Rolled Steel Bar Cold rolled steel is produced by a rolling metal forming process where the metal stock passes through one or more pairs of rolls to provide uniformity and reduce the thickness of the metal. If the temperature of the metal being rolled is below its recrystallization temperature, the process is called cold rolling.

1. Use solid 45# carbon or 40Cr steel as raw material. 2. Tensile Strenth is more than 540MPa, 630MPa and 720MPa. The standard rebar threaded coupler is suitable for connecting two bars of the same diameter, where one bar can be rotated. It comprises an internally threaded sleeve with two right hand threads which are tapered towards the middle of the coupler. The bar ends are square cut and thread is onto the bar. A nominal allowance of +25mm should be allowed per threaded bar end for square cutting the bar end. The couplers are generally torqued onto the reinforcing bar in the bar threading shop, the internal threads protected by plastic end caps. The threaded ends of the continuation bar are protected by plastic thread protectors.

Laminated glass railing aluminum base shoe glass Frameless Design: Provides an open view with a sleek, contemporary appearance. Sturdy and Safe: High-strength aluminum alloy base securely holds the glass in place for enhanced safety. Easy Installation: Modular design allows for quick and cost-effective setup. Versatile Applications: Ideal for balconies, staircases, pool surrounds, and outdoor platforms. Shoe Railing System The intuitive shoe railing system provides ideal sight lines and has the quick installation you need. The combination of fully concealed components and simple installation makes this the ideal glass balustrade solution. Favored by architects for its ultra-modern floating glass design, shoe railing system eliminates vertical supports, enhances sight lines and creates the illusion that the tempered safety glass panels are separate structural elements. It is particularly popular in residential projects such as penthouse balconies and rooftop terraces because it provides unobstructed views and doesn't block the sunlight, making the space feel more spacious.

Glass Balustrade Systems Glass balustrade systems are impressive and represent a flexible modern design solution. Frameless glass balustrades perfectly comply with a popular minimalist aesthetics. We will use the highest-quality hardware compliant with building codes. Our glass balustrade systems contribute to creating a clean, comfort and unobstructed view. It is commonly made with tempered monolithic glass or laminated glass, which is not only safe for the railing use but also allows natural light to flow into the room. The enhanced natural lighting results in better aesthetics and elimination of shadows, and additionally reduces artificial lighting demands, helping cut both electricity bills and carbon emissions.
